if they contain invalid data we no longer continue in and return a 400 Bad Request. This stops potential HTTP desync/HTTP request smuggling. Thanks to Zhang Zeyu for reporting this issue. See https://github and values such as 0x01 and +01 are no longer supported. This stops potential HTTP desync/HTTP request smuggling. Thanks to Zhang Zeyu for reporting this issue.

example See https://github.com/Pylons/waitress/issues/359 and https://github.com/Pylons/waitress/pull/363 In Python 3 OSError is no longer subscriptable, this caused failures on Windows attempting to to find an socket that would work for use in the trigger. See https://github.com/Pylons/waitress/pull/361 Fixed an issue whereby BytesIO objects were not properly closed, and thereby would not get cleaned This led to potential for random memory spikes/memory issues, see https://github.com/Pylons/waitress/pull/358 and https://github.com/Pylons/waitress/issues/357 .
